MILK COOLER.

-it appertains to make and use the same.

This application constitutes a continuation 1n part'of our allowed U. S. application VSr. NO.C\6S,GBG, tiled October 15, 1923 and allowed Jan. 26, 1925 but formally aban- 1925, in favor ot the present case. i i .i

lt is well known-that bacteria in milk will rapidlymultiply lromthe time the milk is drawn from the cows until itis cooled, and as considerable time usually elapses between the milking and cooling operations, the bac teria count rises to such an extent as to greatly decrease the value of the milk. An object of our original application was to provide a novel form of milk cooler adapted to receive the milk directly Vfrom a milking machine, tor the purpose of immediately cooling it and thus keepingr thebacteria count at a minimum. This same object relates also to the present application.

Another object of both the original application andthe present case, is toprovide a cooler mounted on a truck for easy move- Vment to the numerous points at which itis to be used, the truck being of such construction as to lower the cooler when receiving the milk and tol raise it when the milk .was to be discharged into a can or other receptacle.

ln carrying out the invention, we employ :in icc containing casing, a milk container within said casing having a milk chilling'- tween saidcover and the body portion of the tube adapted to receive ice from the conlainer, and a milk tube extending across the. container over said milk chilling tube, said milk tube having' an outlet for the milk.

' Further objects are to provide 'for making the milk container absolutely air tight when. the cooler is' coupled to a milking machine; to provide novel mounting means .for the milk tube, permitting it tobe readily taken out of the milk containerand sterilized; to

make provision whereby the entire milk container nay'be easily removed from' lthe v'jesingtor sterilization, to-` provide a-construction `-in which the supply g otice in the outside "casing may be replenished il necessary whileV the cooler is receivi ing milk, without the necessity of disturbing" the air tight nature of the milk container; to provide. a construction which readily adapts the cooler Yfcruse with the ordinary pulsator of a milking machine; andV to provide a cooler which `will be generally desirable and ,eiiicient W'ith the foregoing in view the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings. l

Figure l isa vertical transverse sectional yview as indicated by line 4-4 ot' Figure` 1.

Figure 5 is a perspective view of the truck. v

In the form o'liconstruction selected for n illustration in the present application, the

container 8. To normally holdL the cover 4 tightly closed, yetto permit itto be easily detachedvhen desired, any-suitable means may be employed. For illustrative vpurposes, we have shown bolts lb pivoted to the` eXte-rior of the container .body and swingable into and out of 4notches 4" in the gasket 4a of rubber or other desired i edge portion of the cover Ll, said boltsfhaving thumb nuts 4d. Y

The bottom `of the milk container 3 is .provided with appropriatesupports 5 which may, weltbein thetorni of arched bars to rest upon thebottoin of the ice casing 1, so as to support said container in spaced relation with the bot-tom of said casing. The supports may either besecured to the container 3 or the casing 1, but they are preferably free of attachment with one ortho other, so that the entire container may be removed from the casing for sterilizing purposes. y l v Ertending horizontally across the 'casing 3 from one end wall thereotto the opposed end wall, we have shown a pair of milk chilling tubes 6 which' communicate with the casing 1 to receive ice from the latter. lAbove these tubes'li, two milk tubes 7have been shown eitjending from end to end of the container 3, said tubes being adapted to receive milk from two pipes 8. when the cooler is receiving` milk'froin two milking ii'i'zicliiiie p'iilsators. It onlyone pulsator is to be used with the machine however, only one ot' the' pipes 8 and one or' thestubes 7 will function' and the other pipe 8 will then beplugged. Along its lower side, yeach milk tube 7 is forinedwith milk discharge perorationsv 9 'which Adirect the milk downwardly onte Vthe chillingtube l(5,.so that the milk .may run arciind the exterior oi' the latter in a thin film, and willthus be effectively chilled as soon as it is discharged. Moreover, it will b e seenthatthis chilled in-comingmilk is maintained at a` low temperature by the ice surrounding thecontainer 3.

In the preferred forni of construction, the ends ot'ea'ch milk tube y7 are closed by removable caps 10 which preferably fitfrictinally over said ends. These caps are removably engaged with seats -11 which are provided n the inner sides of the 7end walls of the milk container 3, said seatsbeing preferably Usliaped as shown vin Figure Ll. One cap 10V of each tube" 7, isfforined with an opening-,1Q to loosely receive the inner end 'ot bthe adjacentmilk inlet pipe 8, this in the wall of the ice casing 1, and being threaded as at 1e through an opening in thcrinilk container wall, but passing loosely through the opening' 12. By this association of parts, each pipe 8 may readily be re inoved, so that the tubes 7 may be taken from the-apparatus for sterilizing purposes,

it being obi ious that the 'cap 1'0 maybe renioved to permit a incre thorough 'cleaning The readilyco-act with the usual bucket used in connection with the pulsator- The m-ilk container 3 is provided with au appropriate milk outlet pipe 15 having a spigot 15, one or'both of these parts being preferably detachable by an appropriate threaded joint, so that they will not inter- ,fere with removal of the container 3 from hef discharged, for instance into an ordinary can C, the cooler 'must be raised sutliciently to permit the insertion ot' Vthe `can or other receptacle under the spigot 15u. To accomplish all of these'results, we make use of a single truck structure which is preferably, although not necessarily, of the form shown. lVe have illustrated rontand rear axles 16 and 17 having suitable rollers or wheels 18. Posts 19 rise rigidly from the axles 16 and 17l and are pivot'ed at their upper ends to vlongitudinal barsQO, the posts of each axle being connected by av transverse bar 21 which abuts the lower edges ot' the bars 2 0 Ywl'ien the truck is in raised position, as seen in Figl, the posts 19 being then slightly beyond dead center, as shown. A suita- :ble [1 -shaped tongue 'or handle 22,' has its .ends 23 suitably secured to the rontyposts v19 or 'to the front axle 17, and longitudinal Vltongue or handle, to the position shown in Fig, the front posts 19 Will be tilted, and the'bars 2O and 24 will'produce tilting or' the rear posts 19. Thus, the entire truck structure isvertically collapsed to lower the tank land theparts associated therewith.

Then the apparatus is in a loweredposition as shown in Figs. 3 and fl, it is in readiness to receive milk 'from the milking maf chine pulstor or pulsators and itL will effectively co'el suchmilk and 'retain it at alow temperature until -its capacity isl reached. Then, the truck is vertically extended to elevate. the apparatus, a can or the like is inserted under the spigot 15,and the contents 'of the container 3 are drawn oli' and immediately carried l,to a refrigerating cha-mber, unless the milk is Kto Y be immediate-ly hauled or shippedto its destination.

The device -issiniple and inexpensive, lyet i isliig-lrl-.y eiiieient andin every wayfdesiiable,

and ,as .excellent results may be obtained.

trom the general construction shoi'v'iigf-it may ack ioo

izo 'i el'lbe fellowed, nut nitliintheseopeot the.: invention as claimed, numerous changes may be made. It desired, a small hand carried device may be made for hand milking.
